Begonia plant named ‘TMBG1307’

ABSTRACT

A new and distinct cultivar of Begonia plant named ‘TMBG1307’, characterized by its upright to spreading and mounded plant habit; dark green to dark greyed green-colored leaves; freely and continuously flowering habit; strongly fragrant flowers; and large ruffled double-type flowers that are bright orange in color.

Botanical designation: Begonia x tuberhybrida.

Cultivar denomination: ‘TMBG1307’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begoniaplant, botanically known as Begonia x tuberhybrida, and hereinafterreferred to by the name ‘TMBG1307’.

The new Begonia plant is a product of a planned breeding programconducted by the Inventor in Harkstead, Ipswich, United Kingdom. Theobjective of the breeding program was to develop new trailing Begoniaplants with fragrant flowers.

The new Begonia plant originated from a cross-pollination made by theInventor in August, 2010 of a proprietary selection of Begonia xtuberhybrida identified as code number 260, not patented, as the female,or seed, parent and a proprietary selection of Begonia x tuberhybridaidentified as code number 146, not patented, as the male, or pollen,parent. The new Begonia plant was discovered and selected by theInventor as a single flowering plant from within the progeny of thestated cross-pollination in a controlled greenhouse environment inHarkstead, Ipswich, United Kingdom in July, 2011.

Asexual reproduction of the new Begonia plant by shoot tip cuttings in acontrolled greenhouse environment in Harkstead, Ipswich, United Kingdomsince August, 2012 has shown that the unique features of this newBegonia plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environment such astemperature and light intensity, without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘TMBG1307’. These characteristics incombination distinguish ‘TMBG1307’ as a new and distinct Begonia plant:

-   -   1. Upright to spreading and mounded plant habit.    -   2. Dark green to dark greyed green-colored leaves.    -   3. Freely and continuously flowering habit.    -   4. Strongly fragrant flowers.    -   5. Large ruffled double-type flowers that are bright orange in        color.

Plants of the new Begonia can be compared to plants of the female parentselection. Plants of the new Begonia differ from plants of the femaleparent selection in the following characteristics:

-   -   1. Flowers of plants of the new Begonia are more outwardly        facing than and not as upright as flowers of plants of the        female parent selection.    -   2. Flowers of plants of the new Begonia are more fragrant than        flowers of plants of the female parent selection.    -   3. Flowers of plants of the new Begonia are bright orange in        color whereas flowers of plants of the female parent selection        are deep salmon in color.

Plants of the new Begonia can be compared to plants of the male parentselection. Plants of the new Begonia differ from plants of the maleparent selection in the following characteristics:

-   -   1. Leaves of plants of the new Begonia are darker in color than        leaves of plants of the male parent selection.    -   2. Flowers of plants of the new Begonia are smaller than flowers        of plants of the male parent selection.    -   3. Flowers of plants of the new Begonia are bright orange in        color whereas flowers of plants of the male parent selection are        red in color.

Plants of the new Begonia can also be compared to plants of the Begoniapendula ‘Victoria Falls’, disclosed in U.S. Plant Pat. No. 20,653. Inside-by-side comparisons, plants of the new Begonia differ from plantsof ‘Victoria Falls’ in the following characteristics:

-   -   1. Leaves of plants of the new Begonia are darker in color than        leaves of plants of ‘Victoria Falls’.    -   2. Flowers of plants of the new Begonia are twice as large as        flowers of plants of ‘Victoria Falls’.    -   3. Flowers of plants of the new Begonia are strongly fragrant        whereas flowers of plants of ‘Victoria Falls’ are not fragrant.
